.zell Qt the United St t residing eL rose Park, injthe eounty ofjMon-tgome ry and State of Pennsylvania, have invented certain new and useful Improvements inYlVindoW-Sash-Assemhling Apparatus, whereof the following is a speeification, reterenee heinpilhad to the accompanying drawings.

y invention relates to apparatus useful I inassemhling and riveting together the. composite members of .I'netalho' W1I1dQW sashes.

Sash structures of the type referred to are ordinarily composed of rails ofstandard .cross sectional shapes eomprehending not only the mun'tins and .mullions, ,but the perimetrical rails oi thesash as Well. Itis generally customary to assemble-as a unit, .those elements which constitute the muntins and mullions, and then to attachthe perimetv rical rails about said unit in completing the sash frame. The muntins and mullions, according to standard practice, are formed at 4 their ends With shouldered terminal tongues adapted to be inserted through appropriate apertures in the .periinetrica-L railsof the sash the protruding portions ofsaid tongues cientlyeifeoted. This desideratuinl attain hyuse, of pneumatically"operated riveting device adapted to ,head' o verthetong'ues of the nuntins and 'inu1li oi1s, and .--infassoc-iation. mean 'wherehy thesash frfaines. may be supported in suspension for ready rnanipulaif tionin heingshifted nan one position t 5 other in the riveting device preparatory Other objectsjanclfattendant advantages of invention .Will beoome read ly apparent from" the detailed desoription' which follows. an. view of In the drawings, I. is a pl lin indovvf's'as'h frame as'se ronlVem'ently .e nbo' the numerous,riveting.operations involved. v

The muntins and mullions MM have a standard cross sectional configuration such as best shown in Figs. VII and XI, and are united to form an insert unit to which the perimetrical rails are subsequently attached. The muntinsand mullions MM have shouldered terminal tongues TT which are inserted through appropriate apertures A in the perimetrical rails P, see Fig. VIII. The protruding ends of the tongues T are thereupon headed over upon the perimetrical rails by riveting to effect permanent union of the sash members.

' Referring now more particularly to Figs. II to, VI inclusive, it will be noted that the I riveting device 2 there shown in detail has i 20 a base or bed plate 4 which is supported preferably at a slight elevation from the floor, by means of a separate sub-base 5. The base or bed plate 4' has rising from it, a pair of spaced, integral, standards 6--6, which have formed upon their upper ends, aligned bosses 7-7 respectively. Said bosses are axially bored to receive a fixed pivot-shaft 9 which serves as a common fulcrum for pincer or clamp arms 10 and 11. The jaws 12 and 13 above the fulcrum of said arms are respectively provided with replaceable face plates 15 and 16, which are serrated as clearly shown in Fig. II, so as to securely engage the sash members which areto. be riveted. The lower ends of the arms 10 and 11 are connected by toggle links 17 and 18, which are interpivoted at 19, and there coordinated with the piston rod 20 of a vertical pressure fluid cylinder 21 mounted to the base 4 centrally in the interval between the frame standards 6--6. From Fig. IV, it will be observed that the cylinder 21 is of the dou ble acting type, it being accordingly provided with ports 22 and 23, which communicate wit pipes 24 and 25 respectively, under control of suitable inter osed rotary valves 26 and 27 capable of a mitting and exhausting motive fluid to and from the cylinder ends. Said pipes lead from an appropriate source ofwsupply of fluid pressure (not shown) preferably compressed air.

In order that the valves 26 and 2.7 may be simultaneously operated, their actuating levers 28 o and 29. are interconnected and coupled by means of a link 30 with a bell crank 31 which is in turn connected by a link 32v with a fort treadle 33. The treadle mechanism isreturned to normal position ,afterIreIease ofthe treadle 33, by a coiled tension spring 34.

In the course of assembling the window sash, the muntms and mullions M are successivel engaged betweenthe jaws 12 and '13 o the pincer r"clamp arms 10 of the automatic rivetin comprehensively at 35. aid tool, as Wlll and 11 as shown in Fig. IV, while the metrical rails P are headed over by means tool indicated he observed from Fig. II, is axially aligned in the plane of meeting of the jaws 12 and 13, and its barrel 36 has formed integrally with it, a cylindrical lug 37 which fits within a seat 38 in the top of the frame standard 6 and is held by a clamp plate 39, mounted to said standard by screw 'boltes 40. By this arrangement, the tool 35 may be shifted in an axial direction, as desired, for adjustment with respect'to the pincer or clamp elements. Ad'ustment of the tool 35 in a direction towar the jaws 12 and 13 of the pincer clamp is facilitated by aid of a set screw 41 which is carried in the boss of a plate 42 bolted to the standard 6. The screw 41, it will be noted, is axially aligned with the cylindrical lug 37, and engages the end of a stop plug 43 inserted WltlllIl the bore of said lug.

While the tool 35 is of standard construction, in order that its operation with reference to the special purpose for which it is here used may be more readily understood, I will proceed to describe in detail, certain of its adjunct-ive parts. A sleeve 45, shiftable automatically with respect to thebarrel 35 ot' the tool, has clamped upon its outer end, a yoke 46 which is bifurcated as clearly shown in Fig. II. The extremities of the yoke carry abutment stops 474-47 which, during the riveting operation, bear against the perimetrical rail P of the window sash and hold the same in engagement with the shoulder of the muntin or mullion whose tongue is being headed by the rivet set 4-8. Normally, the sleeve 45 is held in retracted position by means of a spring 49 which, for the most part, is housed within the bore of the lug 37 of the tool, and has its anchorage, at one end, in the lug 43, while its opposite end is attached to the yoke 46. The tool 35 is controlled by means of a rotary valve 50 interposed in a compressed air pipe line 51, and has a handle 52 whereby it may be manually operated. a

After a muntin or mullion is properly engaged within the pincer'clamp by pres sure applied to the arms 10 and 11 of the latter under control of the foot treadle 33, and the perimetrical rail P properly placed with relation thereto, the operative turns the handle 52 of the valve 50 to admit compressed air to the tool 35, whereupon the sleeve 45 is immediately projected so that the abutment stops 47 firmly engage the perimetrical rail P while the reciprocations of the upsetting tool 48 efi'ect the heading over the projecting tongues T in a manner which is clearly obvious fromiFi II. The vari us *n s yehifti g h the device 3 previously mentioned.

As best shown in Figs. 1, IX and X, the crane arms 55 of the'device 8 overhang both the table 1, and the riveting device 2, and is swingable about afixedpivot rod indicated at 56. Secured to the arm is a rail 57 which serves as a guidefor a shiftable roller carriage 58 wherefrom is hung, preferably by means of chains 59-59, a horizontally disposed attachment frame 60. Said frame carries a number of sash engaging devices 61-61 which areadapted to engage individual muntins and mullions of the window sash, and which, as will be presently explained, are relatively adjustable, so that they may be spaced at different intervals in accordance withthe spacing of the. muntins and mullions of the sashes of different sizes. The chains 59-59 are not directly attached to the carriage 58. but to one end of an in terposed hand lever 62 fulcrumed about a pin 68 spannedbetween the sides of a yoke piece 65 which is bolted orotherwise secured to the carriage; By means of the hand lever '62, the attachment frame may be raised.

or lowered to facilitate picking up of the window sash from the'work table and vice versa in the manner suggested in Fig. X.

i In order that the sash mav be maintained in free suspension while being transferred to and from the work table, and for convenient manipulation in the riveting device as aforesaid, I provide a locking means in the form of a hook 66 which projects from the attachment frame 60 and is adapted to engage the hand lever 62 as clearly shown in Figs. IX and X. A. very slight lateral motion of the hand lever is sufiicient to bring about disengagement thereof from the looking hook 66 when the window sash is to be deposited upon the work table after the completion of the riveting operations.

The sash engaging devices 61, of which there are in the instance shown (Fig. 1) four in number, are arranged in groups of two each. These groups are respectively carried-by the parallelly extending-T rails 67-67 of the attachment frame. The sash engaging devices of each group are adapted to be simultaneously operated by means of sliderods 68-68 mounted in appropriate brackets 69-69 secured to said rails. For the, purpose of limiting the shifting allowed the rods 68-68, the latter are respectively provided with heads 70-71 which cooperate with the end brackets 69-69 of the series, and are normally yieldingly held in the illustrated positions by springs 72-72 which, at one end, abut againstthe interme-' diate brackets 69. and at the other end, engage collars 73-73 on said rods.

Coming now to the sash engaging devices illustrated to best advantage in Figs. XI andXlI, it will be noted that these devices are similar in construction and that each of them comprises a bracket 75 which may be set in different adjusted positions along, the T rail 67 by means of a clamp screw 76 for a purpose previously alluded to. Fulcrumed about a common fixed pivot secured in a depending arm 77 of the bracket 75, are tong members 78 and 79 whose hooked ends are opposed so as tobe capable of engaging individually between them, munt-ins.

or mullions (as the case may be) of the window sash. The extended portions of the tong members 78-79 above their common fulcrum are respectively slotted for cooperation with projections in the formof rollers 80, 81 extending laterally from one face of a disk 82. Said disk is mounted for rotation to an upwardly extending arm 83 of the bracket 75. Projecting from the opposite face of the disk is a pin 85 which is engaged within the groove of a collar 86 on the slide rod. The collar 86 is adjustably mounted on the rod, so that it may be shifted in accordance with the positioning of the bracket 75 as aforesaid. From Fig. XI, it will be apparent that movement of the rod to the left will induce counter-clockwise rotation of the disks 82 of the two sash engaging devices there shown, and, through the interposed instrumentalities already described,

separation of the hooks of the respective tong members 78-79 to release the window sash when the latter is to be deposited on the work table. Manipulation of the control rod 68 is unnecessary when the sash is initially engaged since the tong members 78-79, by reason of the complementarily disposed curvature of their hooks, yield readily to separation as they engage the muntins or mullions of the sash when the frame 60 is lowered. If further adjustment for accommodation of different sized window sashes should be desired, this may be had by adjusting the rails 67-67 along the bars 87-87 of the frame 60. To this end, I have attached to the lower face of the rails 67-67, stirrups 88-88 which extend about the bars 87-87, and serve as appropriate guides,-while the adjustments are made, see Fig. X. Such adjustments are fixable by means of set screws shown at 89-89 in the illustration last referred to. The bars 87-87 are made tubular and preferably rectangular in cross section so as to be substantially rigid against bending.
